Plate rail was an early type of rail and had an 'L' cross-section in which the flange kept an unflanged wheel on the track. The flanged rail has seen a minor revival in the 1950s, as guide bars , with the Paris Métro ( Rubber-tyred metro or French Métro sur pneus ) and more recently as the Guided bus .
A railway track (CwthE and UIC terminology) or railroad track (NAmE), also known as permanent way (CwthE) [1] or "P Way" (BrE [2] and Indian English), is the structure on a railway or railroad consisting of the rails, fasteners, sleepers (railroad ties in American English) and ballast (or slab track), plus the underlying subgrade.

Crosslevel (or 'cross level') is the measurement of the difference in elevation (height) between the top surface of the two rails at any point of railroad track. The two points (each at the head of each rail) are measured at by the right angles to the reference rail. Since the rail can slightly move up and down, the measurement should be done ...

This format is now in place over 99% of the first-class main lines in Britain, although the CEN60 (60 kg/m) rail section was introduced in the UK during the 1990s. This has a wider rail foot and is taller than the 113A section so is incompatible with standard sleepers. Track renewal trains have now replaced labour-intensive permanent way gangs ...
Standard gauge is defined both in metric and in imperial units. It is the most widely-used gauge worldwide, ab out 60% of the world uses this track.

Quadruple track section of the West Coast Main Line, England. A quadruple-track railway (also known as a four-track railway) is a railway line consisting of four parallel tracks with two tracks used in each direction. Quadruple-track railways can handle large amounts of traffic, and so are used on very busy routes or sections.
